  • Handling and assembly equipment and method
    Patent number: 7055609
    Abstract: A handling and assembly system and method for use in deploying tubing in a subterranean environment. A framework is used to linearly engage sequential tubular members as a tubing string is formed and run into a subterranean environment. The system also facilitates the disassembly of the individual tubular components from the tubing string.
    Type: Grant
    Filed: June 2, 2003
    Date of Patent: June 6, 2006
    Assignee: Schlumberger Technology Corporation

  • Technique for expanding tubular structures
    Patent number: 6688397
    Abstract: A system for expanding tubular structures. The system comprises a mandrel that is moved through the center of a tubular structure to increase the diameter of the tubular structure via deformation. The system utilizes an expansion device having a mandrel with multiple segments moved between a contracted state and an expanded state. In one embodiment, the mandrel segments are spring biased to permit a degree of independent movement of each mandrel segment with respect to the other mandrel segments.

  • Nesting vise
    Patent number: 5044236
    Abstract: A nesting vise for holding bundles of stock comprising a base with a fixed jaw and a movable jaw mounted thereon, both jaws having faces with apertures therein. A strap is provided which extends between the two jaws through the apertures. A lock is provided to hold the strap on one end, and a strap tightener is attached to the other end of the strap which tightens and holds the bundle of stock, resulting in even radial pull towards the center of the vise so as to locate all of the pieces of stock in the bundle and locking them together.
